Charging the battery
Battery power is needed for
•
the real-time clock,
•
the integrated chip card reader and
•
the screen.
Each time the DLKPro is plugged into the computer, its
battery is automatically charged. During charging, the
LED on the DLKPro flashes orange.
Battery power is not needed to download digital
tachograph data. The download will function irrespective
of the battery’s charge level. If the charge level is very
low, however, use of the screen display will be limited or
even impossible.
If possible, leave the DLKPro plugged into the
computer when you finish working with it – this will
charge the integrated rechargeable battery e. g. for
the next card download.
Note
: You cannot operate the screen during data
download.
Note
: Before you use the DLKPro for the first time,
please charge the battery. The battery is fully charged
after approx. 2 hours.
If the battery charge level is well below the limit of 30 %,
the LED will flash green/red every 30 minutes for around
3 seconds, even if the DLKPro is not being used.
The battery cannot be charged while data is being
downloaded.
Note
: To save battery power, the DLKPro switches
itself off automatically after 20 seconds of inactivity.
Tip
: If you use a USB hub as a DLKPro connection,
make sure that the hub has its own power supply.
Otherwise the DLKPro’s battery can only be charged
with a minimal charging current.
